End of mourning under review, as exemplified in this clue? (6)
I believe the answer is:
gerund
'exemplified in this clue?' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'end of mourning under review' is the wordplay.
'end of' says to take the final letters.
'review' indicates anagramming the letters.
The final letter of 'mourning' is 'g'.
'under' is an anagram of 'erund'.
'g'+'erund'='GERUND'
'as' is the link.
Can you help me to learn more?
